两部类结构比与第Ⅰ部类优先增长等之间关系的数理证明

本文首先给出结论,然后给出严格的数理证明,最后通过实际计算对数理证明进行验证。结论研究产业结构最简单的情况,将其分为两大部类。根据马克思的再生产理论构造经济增长模型,通过严格的数理证明可以得出如下结论: 结论一:如果只提高两大部类的有机构成。

马克思两部类扩大再生产模型中的投资乘数

以马克思的两部类再生产理论为指导,联系国民经济核算统计的口径,借鉴运用经典的投资乘数研究方式,可以得出,马克思两部类扩大再生产模型中的投资乘数产生条件就是马克思扩大再生产条件VⅠ+MⅠ>CⅡ,由此推导出的乘数表达式与经典的投资乘数具有相同涵义。

运用马克思的扩大再生产模型研究奢侈品供需

以马克思《资本论》中的奢侈品供需原理为指导,把奢侈品界定为被特定主体消费的独特消费品,解析包含奢侈品供需的社会再生产。针对马克思的两部类扩大再生产模型所具有的特殊结构,对马克思《资本论》中提出的包含奢侈品供需的简单再生产的实现机制进行提炼和扩展,建立包含奢侈品供需的社会再生产线性方程组。首先,运用这个方程组,解析包含奢侈品供需的简单再生产,推导得出各部类及分部类新创造价值之间的比例、剩余价值的使用比例与各部类、分部类的资本有机构成和剩余价值率之间确切的对应关系式。其次,运用这个方程组,解析包含奢侈品供需的扩大再生产,推导得出一般情形下方程组解的表达式。最后,引用和借鉴《资本论》举两个数例,对所推导得出的各个表达式进行数值计算验证。

Tectonically deformed coal types and pore structures in Puhe and Shanchahe coal mines in western Guizhou

To evaluate the effect of tectonic deformation on coal reservoir properties, we provide an analysis of the types of tectonically deformed coal, macroand microscopic deformation and discuss pore structural characteristics and connectivity based on samples from the Puhe and Shanchahe coal mines. Our research shows that the tectonically deformed coal mostly includes cataclastic structural coal, mortar structural coal and schistose structural coal of a brittle deformation series. The major pore structures of different types of tectonically deformed coal are transitional pores and micropores. The pore volumes of macropores and visible fracture pores produced by structural deformations vary over a large range and increase with the intensity of tectonic deformation. Mesopores as connecting passages develop well in schistose structural coal. According to the shapes of intrusive mercury curves, tectonically deformed coal can be divided into parallel, open and occluded types. The parallel type has poor connectivity and is relatively closed; the open type reflects uniformly developed open pores with good connectivity while the occluded type is good for coalbed methane enrichment, but has poor connectivity between pores.

Arg-X Activity in Trypsin-like Complexes of the Nuclear Rroteins in the Suprastructures of Interphase Chromatin During Induction of Growth Morphogenesis Mature Germs of Wheat

The purpose of this study was to analyze spatio-temporal dynamics of localization of protease-sensitive sites Arg-X in non-histone and histone blocks of heteropolymer suprastructures （nucleoplasm, chromatin, nuclear matrix） as possible zones affecting the conformational rearrangements of the total interphase chromatin at the induction of increasing morphogenesis of mature embryos-germs of spring and transformed from its winter wheat. Germinated embryos-germs were detached from endosperm after 24 hours from the start of soaking. Cell nuclei have been allocated from embryos-germs and cleared, and then from their heteropolymer suprastructures （nucleoplasm, chromatin loosely bound with nuclear matrix and chromatin tightly bound with nuclear matrix, and nuclear matrix） were extracted by increasing ionic strength of solution. From isolated nuclear suprastructures, non-histone proteins were separated from histones using ion exchange chromatography. Trypsin-like complexes from non-histone proteins and histone blocks were isolated using the affinity chromatography. The Arg-X （tryptase） activity was assessed by cleavage of Arg-X bonds in the arginine-enriched protein protamine. Hypersensitivity to the Arg-X proteolysis in trypsin-like complexes detected at the level suprastructures of chromatin tightly bound with the nuclear matrix was shown. The most active changes of the nuclear proteome have occurred at the level of the non-histone proteins and the core histones （H2A ＋ H2B） （H3 ＋ H4） of induced to growth embryos-seedlings of winter wheat （compared to the initial spring form of wheat）. Perhaps hypersensitivity to the Arg-X activity of the trypsin-like complexes in the non-histone proteins and the core blocks of chromatin tightly bound with nuclear matrix have been entrenched during the transforming of the winter wheat from the initial spring wheat.

生产结构、收入分配与宏观效率——一个马克思主义政治经济学的分析框架与经验研究

现有文献对收入分配调整、经济结构变动和宏观效率提升三者之间的关系鲜有系统性研究。本文将马克思的再生产图式拓展为由固定资本、一般性生产资料、消费资料组成的"马克思—斯拉法"型三部类结构表,并利用中国1987—2015年的投入产出表,刻画投资驱动型增长下收入分配与宏观效率之间的关系。文章测算了中国经济的工资—利润曲线,再根据实际与潜在收入分配结构之间的偏离度,评价了中国宏观效率提升的空间。结果表明,利润率出现了下降的趋势,符合马克思的理论预测;利润率的下降主要归因于外延式增长方式下固定资本投资快速增长引起的资本有机构成提高;对宏观经济效率的分析表明,在传统增长方式之下,改善宏观经济效率的空间极为有限,必须转变经济发展方式,打造经济增长新动能。

意识形态运行机制的时间解析--基于马克思恩格斯的思想

意识形态,作为思想上层建筑,在与社会经济和政治生活相互依存、相互作用的历史过程中,既有并存、互动的共时态关系,又以其相对独立性在某些方面超前或滞后于政治、经济生活的发展,形成自身持续的历时性。它在总体上遵循社会发展的时间秩序,但各组成部分在与经济基础的具体联系中,在反映和言说社会生活的现实状况和历史趋势中,又各有其时间特质,综合地表现为意识形态运行的时间机制。联系意识形态的社会历史属性进行时间逻辑解析,是马克思恩格斯对精神文化现象展开唯物史观研究的重要方法;探析这方面的思想,有助于增进我们理解、建设和治理意识形态的自觉性、科学性。
